Abstract: It is desired to find an alternative way to produce benzophenones or substituted benzophenones which does so selectively and avoids the problems of previous methods that use, for example, large amounts of an aluminium chloride catalyst or nitric acid. 
     In the invention process, a diphenyl methane starting material (DPM) in a hydrophobic phase is oxidised in a photolytic process by contact with an aqueous phase containing greater than 1 mole of HBr and at least 1.5 moles of H₂O₂, both per mole of DPM, the radiation being capable of dissociating bromine to its radicals, and especially using light of wavelength 600 to 250 nm. Preferably, a reaction temperature of around 50 to 65°C is used, the organic solvent comprising a suitably boiling chlorinated carbon or hydrocarbon. The H₂O₂ is introduced progressively into the reaction mixture. The benzophenone product is recovered substantially in the organic phase, whereas most of the bromine/bromide is retained in the aqueous phase which can be re-employed in a subsequent oxidation of DPM, possibly after restoration of the bromide to its initial concentration. 
     In a modification to the process, by suitably controlling the mole ratios of bromide and H₂O₂ to DPM at about 1:1:1, and preferably using a reaction temperature of about ambient to 35°C, the DPM can be substituted by a single bromine atom on the methane carbon also with good selectivity, instead of being oxidised to the benzophenone.

Abstract: The invention concerns a method for regulating the temperature of an adjustable-­temperature and variable-crown roll. In the roll (10), the roll mantle (12), arranged to revolve on the stationary roll axle (11), is loaded by the intermediate of a pressure medium so as to correct the deflection of the roll mantle (12), and, moreover, the roll (10) is heated by means of heating fluid passed onto the inside face of the roll mantle (12). The heating fluid is passed into the roll (10) to the areas of the roll mantle (12) from which heat is removed out of the roll (10) by means of con­duction in the radial direction of the roll, i.e. to the areas in which the direction of the flow of heat is radially away from the roll. From the hot areas in the roll mantle (12), i.e. from the areas from which heat is not removed by con­duction in the radial direction away from the roll mantle, heat is again removed by passing cooling fluid to said hot areas. The heating fluid is passed into the roll (10) so that the heat passed into the roll is distributed in the axial direc­tion of the roll in a corresponding way as com­pared with the flow of heat removed from the roll (10), and cooling fluid is passed to the hot areas in the roll (10) in the same proportion as heat flows to said hot areas from other parts of the roll (10). The invention further concerns a temperature-regulation system intended for carrying out the method.

Abstract: A method for the program controlled longitudinal and transverse cutting-up of plates is described, in which from at least one plate, following an edging cut, an edge strip is detached by a further cut and the remaining plate is then cut up parallel to this cut into a plurality of strip-shaped plate sections, whereupon edge strips and plate sections are conveyed further and cut up transversely relative to the cuts made. 
<??>According to the invention, edge strips produced at the longitudinal cutting-up saw are first collected and fed together to the transverse cutting-up saw only after a predetermined number of remaining plates have been cut up. Consequently, the edge strips produced on cutting up a number of plates can be cut up in one operation, resulting in a considerable increase in efficiency.

Abstract: In a boiling water reactor having discrete bundles of fuel rods (60, 65) confined within channel enclosed fuel assemblies, an improved fuel design of bundles of fuel rods interior of the channels is disclosed. Specifically, partial length rods (60) are utilized which extend from the bottom of the channel only part way to the top of the channel. These partial length rods (60) are shortened with respect to the remaining rods and are symmetrically distributed throughout the fuel bundle with the preferred disposition being in the second row of the bundle of fuel rods form the channel wall. The symmetrical distribution of the partial length rods is at spaced apart locations one from another. The partial length rods extend from the bottom of the fuel bundle and terminate within the boiling region. The total pressure drop is reduced, permitting more fuel rods in the design or a larger fuel rod diameter. The ratio of two-phase pressure drop to single phase pressure drop also is reduced, tending to increase the threshold for thermal hydraulic instability or coupled nuclear-thermal-hydraulic instability. Rod spacers (S2) and bundle tie-plates (40, 42) are provided with larger apertures overlying the partial length rods (60) for further channeling of the steam and reduction of two-phase pressure drop. Most importantly and during full reactor power output, the pressure drop in the two-phase region of the bundle is reduced without substantial corresponding degradation of the fuel assemblies thermal limits.

Abstract: A bundle distribution system (10) comprised of tilt tray carriers (20) coupled in tandem forming a continuous loop, each conveyor (20) being a link in the loop. Vertical and horizontal wheels (27, 25) guide the conveyors along a closed loop path (40) which may include curved and straight sections as well as vertical curves and inclined path sections. Each carrier (20) includes a pivotally mounted tilt tray (23) normally maintained in an upright position. Linear induction motors (LIMs) cooperate with a conductive plate (26a) arranged along the underside of each carrier (20) for propulsion. The LIMs are distributed at spaced intervals along the closed loop track (40), each carrier being a movable element of the motor. The LIMs are operated in parallel and a speed sensor (104, 113) provides feedback for controlling the operating speed to a tolerance of within ± 5%. The cam follower rollers (31a-b) of a tilting assembly follow a movable tilt cam (70) which initially unlocks the tilting mechanism from the locked position followed by tilting of the carriage (21) about its longitudinal axis. Straightening cams (90) on both sides of the track downstream from the opening cam reset the tilted tray and prevent overshooting. The multi-wheel speed sensor (113) assures rolling engagement of at least two of the sensor wheels with at least one of the carts. A top loader (17) which is positioned above the track so as to minimize the space required therefor, is capable of dropping signature bundles (12) onto the desired tray (20) with great accuracy. The tilting cam (70) likewise assures accurate tilting and release of a bundle (12) upon a branching out feed chute (57).

Abstract: In the process according to this invention, a oligonucleotide-dependent amplification procedure is performed on a first sample in which one or more of the four normal ribonucleotides or deoxyribonucleotides in the oligonucleotide is replaced with an exo-sample nucleotide. After amplification, any amplified product that may contaminate a second sample is subjected to a physical, chemical, enzymatic, or biological treatment which renders nucleic acid containing the exo-sample nucleotide substantially unamplifiable in a oligonucleotide-dependent amplification if the same oligonucleotide sequence(s) are used. The treatment may be done as a separate step or it may be done in the presence of a second sample containing nucleic acid sequences to be amplified. The amplified nucleic acid sequences derived from the first sample which contaminate the second sample are not further substantially amplified during oligonucleotide-dependent amplification of nucleic acid sequences of the second sample.

Title: Screw press
Inventor: CLAASEN KARL HERMANN
IPC: B30B1/18
Filed: 1991-06-28
Abstract: The invention relates to a screw press (1) which comprises a press frame (8), a ram (2) actuated by a screw (3), a means (hydraulic cylinder (4)) for the backward movement of the ram (2) and an upper thrust bearing (9) which interacts with the screw (3). During the forming operation, a reaction force is produced in the press frame since the screw is loaded with a compressive force and attempts to deflect upwards. In response to this, there is in the press frame an upper thrust bearing which is arranged above the screw nut. This thrust bearing prevents the screw from deflecting upwards during the loading resulting from the forming operation. To make the screw press more insensitive towards an overshooting of the nominal force or to eliminate such an overshooting as far as possible, the invention proposes that the thrust bearing (9) be supported relative to the press frame (8) by a hydraulic volume (10). <IMAGE>
